Abstract

The complement pathway is an important part of the immune system, and uncontrolled activation is implicated in many diseases. The human Complement Component 5 protein (C5) is a validated drug target within the complement pathway, as an anti-C5 antibody (Soliris) is an approved therapy for paroxysmal nocturnal hemoglobinuria. Here, we report the identification, optimization and mechanism of action for the first small-molecule inhibitor of C5 complement protein.
